IntroductionThe purpose of this Application Guide is to provide direction in applying the Leadershipin Energy and Environmental Design Green Building Rating System Versions 2.1 and2.2 for New Construction and Major Renovations (LEED-NC) to projects in a campus ormulti-building setting such as corporate campuses, college campuses, and governmentinstallations (i.e. there is one owner or common property management and control).The application guide is intended for projects where several buildings are constructed atonce, in phases, or a single building is constructed in a setting of existing buildings withcommon ownership or planning with the ability to share amenities or common designfeatures. Throughout this guide, the term campus is used to represent all of thesepermutations.

LEED-NC Rating System, Support Materials and Tools

LEED is a program of the U.S. Green Building Council (USGBC) that establishes

performance goals in five environmental categories: Sustainable Sites, Water Efficiency,Energy & Atmosphere, Materials & Resources, and Indoor Environmental Quality. Inaddition, a sixth category, Innovation & Design Process, addresses those environmentalissues not included in the environmental categories such as acoustics, communityenhancement, education, and expertise in sustainable design. Many issues specific tocampus projects that are not addressed by the existing credit structure may be includedin the Innovation & Design Process category.

The rating system is supported by the LEED-NC Reference Guide, a document thatprovides additional information and guidance for each LEED Prerequisite and Credit.Consult the LEED-NC Rating System, Reference Guide and www.usgbc.org for more

information on the LEED program, the LEED application process, and the USGBC.

Working in concert with the rating system and reference guide, the LEED-NC SubmittalTemplate is a helpful tracking and documentation tool, as well as a required submittalfor LEED certification. The Version 2.0 Calculator spreadsheets still remain helpful forsome credits.

LEED-NC Application Guide for Multiple Buildings and On-Campus Projects

This Application Guide facilitates using LEED-NC as a performance standard forgreening the design of a building or set of buildings within a campus setting (college,corporate, military, multi-use development, etc.), or a group of buildings certifying as aset. A project involving several buildings may be built all at once, or in phases. Thelatter is especially applicable to large developments.

_____________________________________________________________________________________________

The Application Guide provides an opportunity for building owners to reduce theenvironmental impact of buildings by approaching green building in a broader context.Opportunities for reducing environmental impact may be spread over several buildings,a complex of buildings, or an entire campus or installation. Credits are available to eachbuilding that benefits from the shared amenities. This approach allows for economies of



5/40

scale, enabling more opportunities to reduce the environmental impact of buildings andinfrastructure.

The Application Guide analyzes the intent of each LEED-NC credit and prerequisite as

developed for commercial facilities and interprets them for campus and installationprojects. The greatest opportunities for new interpretations arise in credits associatedwith Sustainable Sites, Water Efficiency, and Energy and Atmosphere. Materials andResources and Indoor Environmental Quality credits have fewer campus-specificinterpretations and remain mostly the same as LEED-NC, merely requiring aggregationof performance results. The total points available under this guide are the same asLEED-NC v2.1 and 2.2 with no new credits added to or deleted from the basic ratingsystem.

This application guide interprets and supplements the LEED criteria for projects. Whereappropriate and unique to the campus or multiple building environment, alternativecampus requirements and submittals that meet the intent of the basic rating system areprovided. The LEED-NC Rating System and the Reference Guide are the governingdocuments for all LEED certification applications.

The LEED Multiple Buildings and Campus Committee

The LEED Steering Committee instructed the Multiple Buildings and CampusCommittee to create an application guide that would be a simple overlay onto LEED-NC. Although simple in concept, this guide will assist many LEED projects e.g. at thetime of release, approximately 7% of all LEED registered project square footage is thatof higher education facilities, which is just one of the sectors served by the guide. TheMB&C Committees ultimate desire is a LEED rating system that can be used to certify

entire campuses and military installations in order to more thoroughly impact thesemarket sectors.

OverviewHow to Use the Application Guide

This Application Guide is designed to complement the LEED-NC Green Building RatingSystem and the LEED-NC Reference Guide. The prerequisites and credits aresupplemented, where necessary, by alternative Requirements and Submittals in orderto apply the rating system to on-campus projects and multiple-build projects. Creditrequirement alternatives in this Application Guide may be used instead of the regularLEED-NC requirements, but are not mandatory as they may not apply in all situations.The USGBCs CIR process also applies to this Application Guide and its requirements.

If appropriate, each prerequisite or credit includes Application Guidance with adiscussion of related technologies and strategies. The Application Guide should beused as a working document that is referenced frequently throughout the designprocess.

Campus and Multiple Building Issues

The most detailed application guidance is necessary in the Sites category, as itpresents the most challenges. Most credits in other categories simply allow the optionof aggregate calculations. Campus settings sometimes have established property linesbetween segments of the campus, but share a common infrastructure between areas.Street lighting within a campus (e.g., lighted walkways) may technically encroach uponan adjacent property within the campus boundary. Similarly, stormwater from thecampus may enter into a common retention pond or treatment facility specifically builtfor the campus. The use of natural treatment processes and distributed approaches are

encouraged in the campus setting. The campus may own a wastewater treatmentsystem and utilize the gray water for irrigation purposes. Streets and right of ways maybe turned over to the local government after completion. Infrastructure and commonamenities can be shared in campus settings and may contribute to performanceachievement, thus helping to capture LEED points. The approach must be consistentlyapplied across the project and all such cases are carefully scrutinized by the USGBC.

Some campus and multiple building projects may be mixed use development where thecampus is developing a portion of the project and a separate party (or parties) isdeveloping the remainder of the project. In such cases, the campus entity may definethe LEED scope in such a way as to omit buildings that will be built by a separate party.

This choice should be made with due consideration of the issues and projects areadvised to keep omissions within the site boundaries to reasonable limits, in particularto parts of the overall project over which the project team will not have control. Whenthe project is one building, the parts of the building within the campus entitys scopemust meet LEED requirements. It is recommended that these buildings demonstratethat specific steps have been taken and guidance provided to insure that future build-out can also meet LEED requirements. The development of a thorough and instructiveset of design guidelines and recommendations, coupled with building infrastructure to

_____________________________________________________________________________________________



7/40

support future LEED build-outs, is encouraged to ensure that the building will performas a LEED building after build-out.

The Certification Process for Multiple Buildings and within Campus Settings

Any project team utilizing this guide simply registers its project under the standardLEED-NC program. A project already registered can choose to use the applicationguide at any time before certification submittal, but should do so as early as possibleduring the pre-design or design stage.

*** Note: The following certification processes are in pilot phase, and may be revised atany time. The most up-to-date version will be posted on the Web site along with thisapplication guide. ***

There are three approaches to certifying buildings in the campus or installation setting:

Certifying a new building within a setting of existing buildings that areconsidered a campus, i.e. there is one owner or common propertymanagement and control.

Certifying a group of new buildings as a package where the entire building setwill be rated as a package and only one rating received. These buildings mayconstitute the entire campus or be a subset of an existing campus.

Certifying new buildings where each new building is constructed to a set ofstandards but will receive an independent rating based on achievement ofcredits beyond the standards specific to that building. These buildings may

constitute the entire campus or be a subset of an existing campus.

Each of these approaches will be discussed separately and registration and certificationprovided for that particular approach.

Certifying a new building within a setting of existing buildings

The certification process is essentially the same as the LEED-NC certification processfor the given building. When certifying a single building under the Application Guide,you may choose campus requirements and submittals in lieu of the standard LEED-NCrequirements and submittals where unique aspects of the campus setting have animpact on the credit affecting the building, e.g. where stormwater managementpractices are campus-wide rather than building-specific.

A reasonable and logical LEED project site boundary must be defined for LEEDpurposes. The project scope of work and the site area affected by the constructiongenerally suffice to inform this definition. The defined site must remain consistent for allLEED credits. The Application Guide provides details on special considerations forshared amenities such as parking (adjacent and, more often, remote) and open space.

_____________________________________________________________________________________________



8/40

Certifying a group of new buildings as a package where the entire building setwill be rated as a package and only one rating received

For entities that construct a set of buildings at once or over a defined time period in a

campus setting, certification of each building individually could result in excessivedocumentation, much of which would be duplicated between buildings. In this case theoption of rating the entire building set may be the best choice. When certifying a set ofbuildings under the Application Guide, you may choose campus requirements andsubmittals in lieu of the standard LEED-NC requirements and submittals where uniqueaspects of the campus setting impact the credit affecting the buildings. The ApplicationGuide provides the methods for calculations and submittals for credits that may beaveraged across the set of buildings and defines which credits must be met by eachindividual building. Using the averaging techniques, where applicable, allows for onerating to be applied to the building set, thereby minimizing documentation. Identify thegroup of buildings with a single name for LEED registration and certification.

Certifying new buildings where each new building is constructed to a set ofstandards but will receive an independent rating based on achievement of creditsbeyond the standards

1. Many campus build entities establish design standards (e.g. campus masterplans and specifications) that will be applied repeatedly to new buildings. Theseelements may be site- or building-specific. The campus build process allowsapplicants to certify a prototype credit set that is intended for repetition onsubsequent projects. The total credits beyond the standards may vary frombuilding to building. Project teams will be permitted to designate prerequisites asprototypes.

2. Certification Review for the First Project:

a. USGBC shall conduct a thorough and complete review of the first project,including prototype credits.

b. The certification submittal shall include all supporting backgroundinformation for prototype prerequisites/credits, and specific guidance willbe developed for these requirements (similar to that created for LEED-NCaudits).

c. Projects will receive a Preliminary and Final LEED Review for allprerequisites/credits pursued, following the published review process.

d. The Appeal process shall be an option for any prerequisite/credit which ispart of this first project.

_____________________________________________________________________________________________



9/40

e. All approved prototype prerequisites/credits will be designated as such inthe Final or Appeal LEED Review of this first project. Any deniedprototype prerequisite/credit shall not be included in the prototype set.

3. Certification Reviews For Subsequent Project(s):

a. Subsequent projects shall be reviewed per the current process, whichincludes up to six prerequisites/credits selected for audit. It will be at thediscretion of the review team whether or not a prototype credit will beselected as one of the up to six for audit.

b. These projects will not be required to submit documentation on approvedprototype prerequisites/credits unless selected for audit in the PreliminaryLEED Review.

c. Failure of an audited prototype prerequisites or credit will result in that

item being denied in the current review. The denied item will temporarilydrop out of the set of approved prototype prerequisites/credits as theproject team will be required to demonstrate achievement of this specificitem for the next three consecutive project application reviews. Onceachievement is demonstrated, this item will return to the prototype set. Ifachievement is NOT demonstrated in any one of the next threeconsecutive project application reviews, the item shall be permanentlyremoved from the prototype set.

d. Appeals will not be permitted for prototype prerequisites/credits insubsequent projects.

e. Prerequisites/credits may be dropped from the approved set of prototypeprerequisites/credits at the project teams discretion. Once removed fromthe set, this item shall not be reviewed as a prototype prerequisite/creditunless it is re-established as such by demonstrating achievement of thisspecific item for three consecutive project application reviews, or per thesteps outlined in #2 above.

f. Prerequisites/credits may be added to the approved set of prototypeprerequisites/credits at the project teams discretion. It must beestablished as such by demonstrating achievement of this specific item

for three consecutive project application reviews or per the steps outlinedin #2 above (for the latter, this action shall occur with an individual projectapplication, and a fee will be associated with adding this item to theprototype set).

The process above assumes that all buildings will be constructed to a specific standardand that credits associated with that standard can receive preliminary approval. Withinthe campus setting, the situation can arise where certain site-related amenities would

_____________________________________________________________________________________________



10/40

not be constructed until after the building project is complete. This may result in somepending credits for buildings. These pending credits cannot be awarded until the actualmaster plan is put into effect and the shared amenities constructed. The individualprojects have two choices:

1. Complete certification of the project with certain credits pending. Thesepending credits may alter the rating of the project. If the project is rated withoutthe pending credits, its rating will be based on only those credits achieved. Oncethe pending credits are available, the project can be recertified and the creditsawarded at that time.

2. Await certification until all credits are available.

The volume/campus build process can also be a useful tool for developers to use whenmanaging a portfolio of buildings. Tracking site-specific issues and benefits of individualcredits or strategies and the lessons learned during the process will inform future design

revisions and decisions. Whether building and certifying projects one at a time, or as apackage of several buildings, project teams must be fair and reasonable in defining theproject scope and site boundaries and be consistent across credit calculations.

SUSTAINABLESITES

SS Prerequisite 1: Erosion & Sedimentation Control

Application Guidance

When the site incorporates more than one building, consider the phasing of construction andhow the control plan will be modified over time to achieve the requirements. Site disturbancemay also be phased and erosion control techniques applied at appropriate times. For largesites, this may be required by law, so effective planning at this scale is highly recommended.

SS Credit 1: Site Selection


The requirements of this credit are very specific to the project site; substitution of other parcelsto meet these requirements is not allowed. Selection of a site for multiple buildingsespeciallyone that is developed over a long period of timewill require effective site layout and planning

to be sure all buildings will be able to meet the requirements.

If the site of a multiple-building development does not fully comply with credit requirements, thenthe buildings can not achieve the credit under a single group certification. However, in such asituation, an individual building is still eligible for the credit if it can be demonstrated that:

1. the area disturbed by the buildings construction activity complies with creditrequirements and this is demonstrated within the LEED application submittal. Thisapproach is expected to be most useful when buildings are being constructed at differenttimes; OR

2. credit requirements are met for the area defined by a reasonable LEED project siteboundary that corresponds to the buildings development footprints or other fair

subdivision method. The LEED application submittal must include thorough justificationfor this artificial site boundary, as it will be closely scrutinized. The LEED projectboundary must remain consistent for all credits. This approach is expected to be mostuseful when buildings are constructed within the same or overlapping time frames.

_____________________________________________________________________________________________



14/40

SS Credit 2: Development Density & Community Connectivity


NC Version 2.2 provides a community connectivity option that is most likely preferable for mostcampus and non-urban settings. Version 2.1 guidance reflects interpretations that providecompliance pathways adjusted for campus settings.

For Version 2.2, Option 2 (Community Connectivity):

Single buildings on a campus and each building within multiple building projects must

comply with the credit requirements as written in order to achieve the compliance path.

For Version 2.1 (and Version 2.2 Option 1):

Requirements

a) Show that the project complies with the Version 2.1 credit requirements as written andincorporating the concepts in the supplemental application guidance section, below.

OR

b) If the site is located in an existing urban area and the contiguous property is over 15 acres

the project may use the campus boundaries in lieu of a documentation circle to calculatedensity.

OR

c) Show that the project complies with a regional or campus master planning effort toredevelop an area with existing infrastructure into a higher density area with an ultimateintended density that reflects desired local development conditions and meets the intent ofthis credit.

Submittals for (c)

To document that the project has achieved credit equivalence, provide the followinginformation in addition to the Submittal Template:

Documentation showing that the project is being located in a previously developedarea with existing development and infrastructure. (New development in a greenfieldwould not be considered appropriate in this case.) Provide information about theexisting development density based on either the documentation circle or theproperty boundaries.

Documentation verifying that the project location is within a designated dense urbanor campus growth area.

15/40


16/40

SS Credit 3: Brownfield Redevelopment


Large brownfield site redevelopments may vary in the amount of remediation required forspecific buildings under consideration. As long as the entire site is considered a brownfield,credit may be given to buildings on portions of that site that are contaminant free and require nospecific remediation for their development footprint.

SS Credit 4.1: Alternative Transportation - Public Transportation Access


Work with the transit authority to re-engineer bus routes and stops to service the site so thateach building is within the required proximity. Consider establishing transit corridors and zoneswithin the campus to ensure availability and access for the entire campus. Either public orcampus bus lines must be in place by the end of construction to receive credit on that basis.Campus bus lines must interface with public mass transit. If there is no local mass transit, thecampus bus line must connect with a commercial bus or rail line.

For rail transit systems that have not yet been constructed, a letter from the transit authority(stating the intent to establish the rail station and confirming funding sources) is sufficient to

qualify for the credit. Campus shuttles to the closest operational station (if local) can be aninterim solution until a new, closer station is in full operation.

SS Credit 4.2: Alternative Transportation - Bicycle Storage & Changing

Rooms


The requirements are applicable to each building in a multiple-build project. When calculatingthe bicycle rack capacity for transients in a non-residential building, address the loadingpossible at one time and not the cumulative loading based on the total transients in a day.Locate the bicycle storage facilities within 50 feet of the frequently used entrances. Transient(e.g. students, in the case of a campus building) occupancy is required to be included whencalculating bicycle storage capacity.

_____________________________________________________________________________________________



17/40

Full-time staff (or staff FTE) may be used to calculate shower/changing room requirements. Forthis calculation, transients are to be defined as visitors to the building for less than 7 hours.Establish overlapping zones within the campus for ready access to shower and changingfacilities.

If the project(s) is a mixed used development including residential buildings and other types ofbuildings, such as barracks complex on a military installation or a residential section of acampus, each building needs to meet the bicycle storage requirements based on its usage andoccupancy.

A project is exempt from the shower facility requirement if all non-transient building occupantsare housed on the same campus as that building (i.e. a military installation), or within a mileof the building(s).

SS Credit 4.3: Alternative Transportation - Alternative Fuel, Low

Emission and Fuel-Efficient Vehicles


Requirements

Provide alternative fuel vehicles (ultra low sulfur diesel, CNG, LNG, electric, fuel cell, E85; oruse average B50 biodiesel in standard diesel engine), low-emission and/or fuel efficientvehicles* for 3% of the full time employees (FTE) in the building(s) AND provide preferredparking for these vehicles, AND have access to a nearby alternative fueling station.

OR

Where the campus has a central fleet operation or motor pool, at least 50% of the vehiclesavailable must be alternative fuel vehicles (as defined above).

Bi-fuel vehicles must utilize the alternative fuel option.

In the case of centralized parking, accommodations for alternative-fueled vehicles may be madeat the central facilities, providing that those accommodations are credited cumulatively to eachbuildings need based on the preceding criteria. The centralized parking must be within mileof the building(s) or serviced by a campus shuttle.

* Low-emission and fuel-efficient vehicles are defined as vehicles that are either classified as Zero

Emission Vehicles (ZEV) by the California Air Resources Board or have achieved a minimum green scoreof 40 on the American Council for an Energy Efficient Economy (ACEEE) annual vehicle rating guide.

Submittals

_____________________________________________________________________________________________

Provide a LEED Submittal Template and (back-up documentation that provesfaculty/staff/students/employees/residents own vehicles via the preferred parking incentiveprogram), a map identifying the location(s) of the alternative fueling facility, and forcampus/installation fleet vehicles provide proof of ownership of, or 2 year lease agreement for,alternative fuel vehicles and calculations indicating that alternative fuel vehicles will serve 3% of



18/40

building occupants. Provide site drawings or parking plan highlighting preferred parking oralternative fuel vehicles.

OR

Provide a LEED Submittal Template with specifications and site drawings highlighting

alternative refueling stations. Provide calculations demonstrating that these facilitiesaccommodate 3% or more of the total vehicle parking capacity. If centralized parking is used,provide documentation that the parking meets the requirements for distance or shuttle service.

Supplementary Application Guidance

The campus environment lends itself very well to centralized parking concepts which may morereadily accommodate preferred parking. A centralized alternative fueling area may be a viablealternative in the case of flexible fuel vehicles. Fleet purchases and/or fuel choices (e.g.biodiesel) may be strategically combined to achieve the performance target. Consider incentiveprograms for faculty/staff/students.

SS Credit 4.4: Alternative Transportation - Parking Capacity


Campuses are often exempt from local zoning laws regarding parking, and thus determine theirown standards. Calculation and documentation for this credit may be done either on a projectby project basis or a campus-wide basis.

Requirements

If applicable local zoning code indicates there are no minimum parking capacity requirements,or if the campus entity is exempt from local codes, size the parking capacity in transit-orienteddevelopments (TODs) according to the minimum requirements by building typology as outlinedin the Portland, Oregon Title 33 Planning and Zoning -Chapter 33.266 for Parking and Loading,Table 266-1 and 266-2 (athttp://www.planning.ci.portland.or.us/zoning/ZCTest/200/266_parking.pdf) AND providepreferred parking for carpools or van pools capable of serving 5% of the building occupants,

OR

For rehabilitation projects add no new parking and reduce the capacity of existing oversizedparking AND provide preferred parking for carpools or vanpools capable of serving 5% of thebuilding occupants.

Accommodations for carpools and vanpools may be made at the central parking facilities,providing that they are credited to only one building or project based on the preceding criteria.The centralized parking should be within mile of the building(s) served or be serviced by ashuttle bus.


_____________________________________________________________________________________________



19/40

The campus environment lends itself very well to centralized parking concepts which may morereadily accommodate preferred parking. An alternative method of establishing parkingrequirements have been provided. It is suggested that the method that generates the leastparking be utilized. Long term master planning of campus parking facilities is recommended. Asuccessful application of demographic analysis of parking facility users will help identify where

parking will work best to serve mixed uses. An example is to locate parking garages where theycan effectively be used by at least two groups or shifts per day, rather than a garage dedicatedto just an 8am-5pm work force

When calculating the carpool space requirement on a campus where no parking is permittedwithin the specific project boundary, it is permissible to meet this credit by providing carpoolspaces outside of the project boundary to serve the 5% of building occupants. These spacesmust not be counted toward other LEED projects. Signage restricting carpool parking only tothis projects occupants is not necessary. The preferred parking requirement is satisfied if acampus shuttle bus route serves satellite parking lots and structures. Calculation anddocumentation for this credit may also be achieved on a campus-wide basis. When using thecampus-wide approach:

If all parking spaces are permitted and designated as residential and commuter, the numberof commuter permits may be used as the basis of calculations for carpool spaces.

The credit can be achieved by proxy if local jurisdictional requirements that exceed thecredit requirements and it is clearly demonstrated in the LEED submittal.

Comprehensive transportation management programs are eligible for an innovation point.

Regardless of the compliance approach utilized, it is necessary to sufficiently promote thecarpool program.

SS Credit 5.1

Version 2.1: Reduced Site Disturbance - Protect or Restore Open Space

Version 2.2: Site Development - Protect or Restore Habitat


Submittals

For greenfield sites, provide the LEED Submittal Template and attach a list of buildingsindicating that each has met requirements.

For previously developed sites where there are multiple buildings in the project scope, enteraggregate data in the Submittal Template, as appropriate.


_____________________________________________________________________________________________



20/40

Consider the aspects of construction phasing and the use of future building footprints for stagingareas and temporary disturbance locations. On projects that are only a portion of a largerdevelopment and artificial site boundaries are defined for the LEED project, be sure that theyare reasonable, logical, chosen with all credits in mind, and that their use is consistent throughall credits. For multiple buildings, consider aggregating any restored previously degraded parts

of the site as larger areas of habitat are more effective.

SS Credit 5.2

Version 2.1: Reduced Site Disturbance - Development Footprint

Version 2.2: Site Development - Maximize Open Space


Requirements

Open space area can be either adjacent to the building(s) or at another location on the campus.It must be aggregated and contiguous, not divided and dispersed. The open space may be atanother campus site as long as it is placed in a permanent reserve status.

Submittals

If there are multiple buildings in the project scope, enter aggregate data in the SubmittalTemplate.

For campus areas where the choice is made to have the open space set-aside not adjacentto the buildings provide documentation showing the requirements have been met and theland is in a natural state or been returned to a natural state and conserved for life of thebuildings.


Open space does not have to be contiguous to the building(s) to which it is accredited. Openspace may be aggregated and set aside as a larger plot of land. The land must be in a naturalstate or returned to a natural state; quads and playing fields do not count towards attaining thiscredit. This may enhance ecosystems and provide a larger piece of habitat. Clustering of

buildings is good practice in terms of concentrating the impact of development in a limited area,leaving more of the site in its natural state, or providing for larger areas of habitat.Establishment of the project boundary with all credits in mind can enhance this process.Vegetated roofs may also contribute to credit compliance if the plantings meet the definition ofnative/adapted.

SS Credit 6.1

Version 2.1: Stormwater Management - Rate and Quantity

Version 2.2: Stormwater Design: Quantity Control


Requirements

The credit requirements may be met using a centralized approach affecting the defined projectsite and that is within the campus boundaries. Distributed techniques based on a watershedapproach are then required.

Submittals

If there are multiple buildings in the project scope, enter aggregate data in the SubmittalTemplate. Demonstrate that centralized stormwater management strategies using distributedtechnologies achieve credit performance requirements.


A master planning approach to storm water management and overall impervious surfacemanagement that is campus-wide or based on the local watershed is preferred over stormwatermanagement planning limited to one project site at a time. The campus setting with largerboundaries and settings allows comprehensive stormwater management techniques to beapplied on a larger scale and with more flexibility. This provides economies of scale and affordsgreater opportunities for clustering buildings, increasing natural settings, and applyingdistributed management techniques cost effectively. Phasing of projects may affect when aMaster Plan is implemented and how the specific building(s) under consideration will beaccommodated.

Thecampus setting with larger boundaries and settings allows comprehensive heat islandmanagement techniques to be applied on a larger scale and with more flexibility. This provideseconomies of scale and affords greater opportunities for clustering buildings, increasingpervious surfaces and natural settings, and applying management techniques cost effectively.

SS Credit 7.2: Heat Island Effect -Roof


Submittals

If there are multiple buildings in the project scope, enter aggregate data in the SubmittalTemplate and provide a list of buildings meeting the credit.


An average of compliance for building roof areas may be used to meet these requirementswhen more than one building is on the site. For each building or for the group of buildings,combinations of high albedo and vegetated roof must collectively cover 75% of the roof area.

SS Credit 8: Light Pollution Reduction


Requirements

Develop an exterior lighting master plan that includes the project site and the surroundingbuildings in a comprehensive manner addressing the safety and security issues of the campusenvironment by sharing exterior lighting amenities while minimizing light pollution and energyconsumption. The lighting master plan must show that it incorporates the credit requirementsas well as the following:

How this plan will reduce light trespass and night sky access and specific projects fitinto the overall design.

How safety, security, and comfort will be enhanced by the use of a master plan.

Submittals

Provide exterior lighting master plan that addresses the project site and buildings andinfrastructure showing how overall light pollution is reduced.

Provide a design narrative from the Architect, Electrical Engineer, or responsible party thatdemonstrates what measures have been implemented for the registered LEED building(s) tomeet the provisions of the exterior lighting master plan in the campus requirements.

If there are multiple buildings in the project scope, enter aggregate data in the SubmittalTemplate. Submit appropriate documentation supporting the design of the rainwater collectionsystem, the landscape design, and the extent of the supplemental temporary irrigation system.


Landscaping in the larger context of the campus provides abundant opportunity to implementsolutions that require less water and for capturing rainwater or recycled water. Large campusesmay consider treating its buildings wastewater to standards for non-potable uses.

While consistency in site boundaries is required, the initial flexibility in site boundary selectionand building clustering options allow for enhanced opportunities for sharing captured orreusable water. The project may also use native plants and other landscape alterations leadingto a lower water demand. A temporary irrigation system may be used during establishmentperiod for landscape.

WE Credit 2: Innovative Wastewater Technologies


Submittals

If there are multiple buildings in the project scope, enter weightedaggregate data in theSubmittal Template.


When the site has more than one building, a weighted average of the site buildings, based onsquare footage, must be used to meet the requirements of the credit. This method ensures thateach building generally meets the performance requirements.

Opportunities of scale may also allow more effective use of rain harvesting techniques orinnovative and economical waste treatment technologies for the building(s) on the site. Options

include packaged biological nutrient removal systems, constructed wetlands, and high-efficiencyfiltration systems.

WE Credit 3: Water Use Reduction


Submittals

If there are multiple buildings in the project scope, enter weightedaggregate data in theSubmittal Template.


When the site has more than one building, a weighted average of the site buildings, based onsquare footage, must be used to meet the requirements of the credit. This method ensures thateach building generally meets the performance requirements.

Opportunities of scale may also allow more effective use of certain techniques in differingbuildings on the site.

Because of the varying occupant numbers in some types of campus buildings (includingstudents, staff, and visitors) an alternative method of calculating this credit may be used.Rather than basing the calculations on the number of occupants, the water use may be basedon the total number of each type of applicable fixtures in the building and the estimated numberof uses for each of these. For example, for public water closets a sample calculation is as

follows: Total Daily Water Use (Public WC) = Total Number Of Fixtures x Estimated DailyUses x Flow Rate(GPF) x Duration

The calculations should use the same fixture count and daily use numbers for the base andproposed case. This provides a reasonable representation of base and proposed case wateruse. Calculations should include all flush fixtures and the following flow fixtures: public andprivate lavatories, public and private showers, kitchen faucets, and laboratory and servicelavatories.

The following as process loads may be excluded: eyewash fountains, emergency showers,water coolers, and water fountains.

EA Prerequisite 1

Version 2.1: Fundamental Building Systems Commissioning

Version 2.2: Fundamental Commissioning of the Building Energy

Systems


Requirements

Each building in a project must independently meet the requirements of this prerequisite.


Every building on the project site must document compliance. An employee in the owner'sorganization, who is not responsible for project design or construction management orsupervision of the project and who has the appropriate credentials, would be the preferredcommissioning authority for EA Prerequisite 1. The documentation for EA Prerequisite 1 maybe from the design firm, but the individual acting as the commissioning authority must not be

responsible for project design, construction management, or supervision.

In the campus setting, other elements and site features associated with a building project, suchas fountains, irrigation system, wheelchair lifts, 'help phones', and exterior lighting systemswhich are not actual part of a building should also be considered for the commissioning process.

Many campus organizations have commissioning requirements for all projects such as a ProjectDelivery Process (PDP) Manual which outlines required commissioning related steps for eachproject phase, from initial scoping to closeout. It is suggested that these types of documents bereviewed for compliance with the LEED fundamental commissioning requirements and bemodified, if necessary, to ensure that the strategies employed by the design team to achieve thefundamental commissioning credit fulfills all requirements set forth by the LEED reference

guide. A local document or manual as well as any specifications that reference the manual maybe submitted along with documentation of how the local manual and procedures specificallymeet or exceed the referenced LEED standard. A local manual may serve as documentationfor the development of the commissioning plan as long as the manual also complies with theLEED reference guide. The intent of the fundamental commissioning prerequisite will be metassuming the applicant provides information demonstrating their standard building practices, asoutlined in the locally-generated procedures manual, meet or exceed the LEED referencedcommissioning requirements.

EA Prerequisite 2: Minimum Energy Performance


RequirementsEach building in a project must independently meet the requirements of this prerequisite.


When designing a group of buildings, orientation and site utilization can have a major impact onenergy consumption. Consider the group of buildings as a whole for the application of passivetempering and alternative energy applications.

EA Prerequisite 3

Version 2.1: CFC Reduction in HVAC&R Equipment

Version 2.2: Fundamental Refrigeration Management


Requirements

Each building in the project must meet this prerequisite. If the building(s) is connected to acentral chilled water system, that system must either be CFC free or a commitment to phasingout CFC-based refrigerants must be in place, with a firm timeline of five years from completionof the project. Prior to phase out, reduce annual leakage of CFC-based refrigerants to 5% orless using EPA Clean Air Act, Title VI, Rule 608 procedures governing refrigerant managementand reporting.

An alternative compliance path for buildings connected to a central chilled water systemrequires a third party (as defined in the LEED-EB Reference Guide) audit showing that systemreplacement or conversion is not economically feasible. The definition of the required economic

analysis is: the replacement of a chiller(s) will be considered to be not economically feasible ifthe simple payback of the replacement is greater than 10 years. To determine the simplepayback, divide the cost of implementing the replacement by the annual cost avoidance forenergy that results from the replacement and any difference in maintenance costs includingmake-up refrigerants. If CFC-based refrigerants are maintained in the central system, reduceannual leakage to 5% or less using EPA Clean Air Act, Title VI, Rule 608 procedures governingrefrigerant management and reporting and reduce the total leakage over the remaining life ofthe unit to less than 30% of its refrigerant charge.

Provide results of third-party audit demonstrating that replacement is not economically feasiblebased a 10-year simple pay-back analysis. AND provide documentation showing compliancewith EPA Clean Air Act, Title VI, Rule 608 governing refrigerant management and reporting.Provide documentation showing that the annual refrigerant leakage rate is below 5%, and theleakage over the remainder of unit life is being maintained below 30%.


If connecting to a central system containing CFC refrigerants operate according to USEPAcriteria and plan for phasing out the CFC refrigerants. The use of CFCs in central plants is anongoing issue for the campus environment. Systems using CFCs are older and less efficientthan newer systems using modern refrigerants. It is in the best interests of all to phase out the

use of CFCs from several perspectives including ozone depletion, global warming potential, andenergy efficiency. When funds are lacking to modernize central chiller plants, the use of thirdparty financing may be a viable alternative if the energy savings from the new equipment canpay for the initial investment. Consider contracting with an energy services company that frontsthe equipment, guarantees savings, and is paid out of a share of the savings.

EA Credit 1: Optimize Energy Performance


Requirements

This credit applies to each building within the project scope. To receive a single rating for agroup of buildings, use a weighted average for the group of buildings based on their conditionedsquare footage, or aggregate the data into one PRM calculation, so that performance isachieved by buildings of varying sizes within a certifying group. Each building must still meetEA Prerequisite 1 and may receive its own rating if that is desired.


Consider energy sources such as waste heat or recovered resources. Reduced energy cost

may reflect the effect of time-dependent valuation of energy (time-of-use) rates or demandcharges when working in conjunction with permanently installed efficiency or storage systems.Environmental impacts result from the operation and expansion of energy infrastructure both onand off site. Application of the more efficient combined heat and power systems and energystorage systems may be applied more effectively in the campus environment. Since thebuildings are rated based upon the energy (and its cost) that crosses the building boundary,more efficient central energy systems and thermal storage should be used as the basis ofenergy cost reductions in the calculation of the buildings energy performance. Calculationinstructions for Version 2.1 and 2.2 will be supplied as supplements to the respective ReferenceGuides.

EA Credit 2: On-Site Renewable Energy


Requirements

A group of buildings may be evaluated on a group average, based on square footage, or eachbuilding may receive its own rating.

SubmittalsFor multiple buildings either use aggregate data in the Submittal Template and provide a list ofthe buildings or provide a Submittal Template for each building.


Consider orientation of the buildings as a group for maximum access to renewable energy. Acentral renewable energy system may be more cost effective than individual systems on theseparate buildings. In the case where the renewable energy equipment is not physically located

EA Credit 4

Version 2.1: Ozone Protection

Version 2.2: Enhanced Refrigerant Management


Requirements

Each building in a multiple building project must meet the requirements of this credit in order toachieve it. In a campus setting, even if the project is only a single building, this often involves acentral plant.

Version 2.1: If the building(s) is (are) connected to a central chilled water system, that systemmust be HCFC free or a commitment must be in place to phasing out HCFC-based refrigerantswithin 5 years from completion of the project.

Version 2.2: If the building(s) is (are) connected to a central chilled water system, that systemmust meet the credit requirements.


This credit is problematical to some campus situations where the central system is not ownedby the campus operator. Negotiations with the chilled water supplier may be effective in gettingtheir commitment to comply with v2.1 or v2.2 requirements. For Version 2.2, have the chilledwater supplier perform the required calculations and submit a letter showing compliance.

In the selection of refrigerants, consider their global warming potential as part of the analysiscriteria. A life-cycle analysis that includes the future impact of the Montreal Protocol should

guide choice of refrigerants.

EA Credit 5: Measurement and Verification


RequirementsEach building in a project must independently meet the requirements of this credit.

Submittals

If there are multiple buildings, attach a list of the buildings meeting the credit criteria. SeparateM&V plans may be required for buildings that significantly differ.


Consider adding the functions that meet the requirements of this credit to a central energymanagement and control system for the campus. This would allow a continuous commissioningprocess for the building and maintenance issues could be centrally alarmed and personneldispatched to keep systems in peak operating mode.

EA Credit 6: Green Power


Requirements

Green power may be purchased on a centralized basis and credit attributed to a specific project.This same green power may not be credited to another project.

Submittals

Provide certification that any purchased green power is solely applied as credit to this project. Ifmore than one building is to receive credit, provide data for each building showing the projectedenergy consumption of the buildings and the percentage to be met with green power. If thegreen power is generated by a campus entity, show that it meets Green-e standards.


Volume discounts are available from some Green Tag brokers. Therefore, it may be financially

advantageous to the campus owner if multiple buildings are achieving this credit. Cogenerationfrom renewable sources (that meet Green-e standards) would be credited in EA Credit 2.Consider ID Credits for exemplary performance when 100% of green power content is used forextended periods.

INNOVATION&DESIGNPROCESS

ID Credit 1.1 1.4: Innovation in Design


In the campus setting and with multiple buildings, additional innovative opportunities arise,specifically with infrastructure and site issues. Economies of scale allow for more creativity andapplication of initiatives with larger scopes. The strategies and documentation for achievinginnovation credits related to the site may be duplicated in multiple buildings or multipleapplications for separate buildings, provided a clear description of how the whole site achievesthe intended credits is presented. It must be clear that none of the required areas or facilities iscounted twice. Each credit should be carefully assessed and treated fairly, respective of overallsite issues (e.g., pervious surfaces) versus individual building issues (e.g., roofing). Forexample, if the project is applying for SSc5.2, which requires that permanent open space bedesignated adjacent to the building, the area of this open space must reflect the combinedfootprints of all of the buildings.

An innovation credit is warranted if activities and/or programs inspired by a LEED project areapplied to the campus as a whole, thus delivering correspondingly larger environmental benefit.

ID Credit 2: LEED Accredited ProfessionalNo application guidance is necessary.
